執行yarn命令報錯解決方案“error An unexpected error occurred: "https://registry.npm.taobao.org/”

1. 因為yarn的源是

   https://registry.npm.taobao.org
   

2. 而npm的源是

   https://registry.npm.org
   

3. 查看npm的源

   npm config get registry
   

4. 修改npm源
   方法一：

   npm config set registry https://registry.npm.taobao.org
   npm config set disturl https://npm.taobao.org/dist
   

   方法二：

   yarn config set registry https://registry.npm.taobao.org/
   yarn config set disturl https://npm.taobao.org/dist
   yarn config set sass-binary-site https://npm.taobao.org/mirrors/node-sass
   

5. 添加 yarn源

   yarn add taobao https://registry.npm.taobao.org/
   

6. 代理問題：

   yarn config rm proxy
   yarn config  rm https-proxy
